Specification of Letters Patent.

Patented Dec..3, 1907.

Application filed April 17 1907- Serial No. 3683734.

reference being had to the accompanying drawings.

My inventlon relates to improvements 1n .ash sifters; and an object ofmy invention is to provide an ash sifter which will prove simple inconstruction, cheap 'in'manufacture and efficient in operation.

A second object of my invention is to provide an ash sifter which by itsconstruction will prevent the escape of dust and which, therefore, will.be cleanly in operation.

In the drawings illustrating the principle of my invention and the bestmode now known to me of applying that principle, Figure 1 is aperspective view of, my new ash sifter; Fi 2 is a central transversevertical section; ig. 3 is a central longitudinal section of the rotarysieve; Fig. 4 is a plan view with the door and the sieve removed;"'andFig. 5 is a detail of the sieve construction.

The corners of the wooden casing or box a are reinforced with metalcorner pieces I); and to the top of the box a is hinged the cover acovered with sheet metal d. The upper edge of each side of the box a isprovided with a tongue eadapted to engage in a groove f in the opposededge of the cover a. When the cover is closed down upon the box, thistongue-and-groove construction prevents the escape of dust between thecover and the box. The front of the latter is provided with a door ghinged thereto; and around the opening closed. by this door areprojections h which the edges of the door in its closed positionoverlaps so as to prevent the escape of dust from the lower compartmenti. n this lower compartment is placed a suitable receptacle 7' for theashes which fall thereinto through the metal chute 7c the top of whichdrum.

lines the upper part of the interior walls of the box and makes itpractically fireproof. The box a is provided with suitable bearin sm.

ach head n of the drum or rotary sieve 0 is lined with metal p as aprotection against hot cinders. The sieve is two-part, the part q beinghinged to the part r and being locked in place by the pins 8 each ofwhich passes through a staple t and over a ha'sp u in en-- gagement withthe latter. Extending axially through the drum is a sleeve 1) throughwhich passes the shaft w held in place by the locking nuts x. Upon oneend of the shaft w is suitable secured the crank or handle y. The ends12 of the sleeve 0 are reduced and squared; and upon each squared end ismounted a bar ,2 secured to the head of the (Figs. 3 and 5).

The cover is held in place by the en a ement-of the hook 2 in the eye 3;and the door is held closed by means of the button 4.

The sieve can be dumped by removing it from the box (Fig. 1) andunlockingthe part 9 from the part 1'; or by rotating the drum after theparts q and 1' have been released from each other, when the cinders willfall through the chute into the pail below. Two pails are preferablyfurnished with each sifter, one for ashes and one for cinders.

I claim:

An ash sifter consisting of a casing; a. shaft journaled in said casing;a sleeve mounted upon said shaft, the ends of said sleeve being squared;straps mounted upon said squared ends; and a sieve secured to saidstraps and mounted upon said shaft.

In testimony whereof I hereunto set my hand this 4th day of April, A.1)., 1907,'in the presence of two Witnesses.
